Transformers The secondary of a current transformer is always short-circuited under operating conditions because it avoids core saturation and high voltage induction is safe to human beings protects the primary circuit None of these avoids core saturation and high voltage induction is safe to human beings protects the primary circuit None of these ANSWER DOWNLOAD EXAMIANS APP
Transformers When secondary of a current transformer is open-circuited its iron core will be cool as there is no secondary current hot because primary will carry heavy current hot because of heavy iron losses taking place in it due to high flux density none of above will happen cool as there is no secondary current hot because primary will carry heavy current hot because of heavy iron losses taking place in it due to high flux density none of above will happen ANSWER DOWNLOAD EXAMIANS APP
